PORTABLE WEIGHIN G APPARATUS FOR FARM-WAGONS.

To all whom it may concern: 1 Be it known that I, JOHN D. REED, citizen of the United States, residing at Greencastle, in the countyof Putnam and State of Indiana, have invented certain new and useful Improvements in Portable Weighing Apparatus for Farm-Wagons, of which the following is a specification, reference being had A the claims.

The object of this invention is to provide a Weighing apparatus that may be applied to that class of farm-wagon generally known as an extensible wagon, that is to say, a wagon that is capableof being lengthenedor short ened at p easure to suit the class of material to be transported from place to place. I at tain these objects by means of the weighing apparatus illustrated in the accompanying drawings in which. like numerals of reference designate like parts throughout the several views.

L. in Fig. 18 and, Fig. 18 is a view of the same looking in the direction of the arrow f in Fig. 17.

The running gear of the to which my invention of a portable weighing apparatus is particularly applicable is composed of the front and rear ax es 1 and 2 upon the journal ends of whichare mounted the wheels 3, the forward bolster 4 between which and the forward axle 1 is situated the shim or liner 4 whereby the front portion of the body of the wagon is supported to be level or in the same plane as that of the rear portion, the rear bolster 6 situated on the to side of the rear axle 2 to extend longitudinally thereof, the rear, braces 7 extending forwardly to support the top and bottom guide plates 8 and'S the coupling tongue 9, and the front tongue hounds or braces 10 which extend backwardly of the front axle 1 to support the brace 11 to the rear ends of which hounds the said brace is secured.

The shim 4 is situated upon the top side of the axle 1 and is remanently secured (i said shim 4 restin together bya bolt or center pin 5.

The rear bolster 6 is rigidly and permanently secured to the rear axle? upon which latter it rests. I

The guide plates 8 and 8 are secured to the braces 7 at their forward top andbottom sides at a distancebetween them to permit the rear end of the coupling tongue 9 to be passed between them, thus not only operating as a support for the rear end of said coupling tongue but also servin the purpose of a guide when moving the axles of the ru ear of the wagon nearer to each other or rther apart.

The coupling tongue guide lates 8 and 8 are drilled to receive the coup ing-pin' 12 and the holes 13 are formed in the couphng tongue 9 and are adapted to register with the bores of the said coupling tongue guiding plates, so that when said coupling tongue is' moved longitudinally to either lengthen or shorten the spread or reach of the wheels of the wagon, the coupling-pin 12 mav be passed through'the holes of the guiding plates 8 and 8 and that hole of the couplingtongue registering with said guide plates coupling pin hole to lock the coupling tongue at any desired point of its lengthto prevent it moving longitudinally.

. The body 14:- of the wagon, when in its normal position, rests upon the forward and rear bolsters 4 and 6, and is held and main tained in position thereon by the standards the recesses 22 formed in the front bolster't I on to turn therewith.

15 which are secured at their bottom ends to the bolsters 4 and 6,, i

The guide strips 16 are securedto he outer sides of the sides or wings of the b0 y of the wagon in position' thereon to extend vertically and sufficiently far apart to touch or almost touch the front and rear sides of said standards 15, and the said standards and theguiding strips are provided to cooperate to maintain the body of the wagon in position on its supporting bolsters. 9i p 1 On the inner faces of said standards are the friction bearing-rollers 17 which'areada ted to bear against the sides of the body' o the wagon, sothat said body may be more read ily moved in avertical direction between the said standards 15 when the wei ht of the said body and its contents are app ied to the weighing apparatus. I will now proceed to describe the weigha paratusas applied to farm wagonsland whic is the-essence ofthis invention.

The forwardload carrying levers are comosed of the shorter lever arms 18. and the ong'er lever arms 33. The shorter lever 'arms 18, having the knife bearing edges 19 adapt' ed to bear in the grooves 30- of the plates 28 when the weighing apparatus is in operative gear, are keyed or otherwise secured totheir Jarbors 20 to turn are journaled in the bearings formed in the fulcrum plates 21 which plates are secured in The arbors 20 are prolonged so that the bosses 31 of the longer lever arms 33 maybe fitted and keyed or otherw se secured there- 'The rear load carr 1g leversare similar to the forward load carrying levers "and are also con'l osed of the shorter lever arms 23 and the onger lever arms 34.' The shorter lever; arms with the knife bearing edges24 w ich are "adapted to bear 29 and thesaidshorter lever arms are keyed in the grooves 30 of the plate orotherwise. securedon thefarbors 25 to turn ,bearings' formed in the. which plates are secured the recesses 27- therewith, and said arbors.

23 are rovided therewith and said arborsafe journaled in formed inthe rear bolster 6.' 'The arbors; 25 are also" prolonged's'o that the bosses'3'2 of the longerlever arms 34 may befitted and fulcrum plates 26" keyed or otherwise secured thereonfto'turn tend through the said key-way or slot to is composed I the longitudinally slide longitudinally of said-slot, and said key is secured in the endof the telescoping solid portion 42 0f said extensible shaft, so that the forward tubular portion and the rear telescoping portion of saidshaft rotate together as if composedof one integral piece.v

The looped ating lever arms 37, and 38 are the purpose of permitting1 t tongue 9 to pass throu h t e sweep of said levers wit interfering with their movement.

- The front end'of the tubular ortioiir41of provide for e cou ling.

end portions'45 of the ,coo 'er- 1 P ane 9 f out obstructing .or

the extensible-shaft is journale injfthefibore l of the boss iii-secured to the platej47,"and a. collar 48 on the front'end of'said'shaf t'141' retains the latter in its bearing andfprevents it from moving longitudinally in either'direclion.

The rear or solid telescopingportion 42 of .said,extensible shaft is journaledhat or near,

pend therefrom to connect at their lower ends to the weigihlt beam or scalebe'a'm 59. April 60 having a .to said weight or scale beam 59:

. On the end of the longer eccentric pin 56 ife bearing edge61. connects the." lower ends of the depending'links '54Jan'd55 nected to the weighing secured a handle 62 which is provided for the purpose of rotating the eccentric 58 to elevate or lower the eccentric pins 56 and 57 to raise or lower the weight or scale beam 59 to place the weighing apparatus into or out of gear.

l Vhen the weighing apparatus is not required to be used to weigh the contents of the wagon it is readily released by turning the eccentric 58 to lower the eccentric pins 56 and 57, shown in Figs. 18 and 14, to permit the weight or scale beam 59 to drop suiiiciently to exert no influence upon the weighing apparatus. The weight or scale beam 59, by the lowering of the eccentric pins 56 and 57, is dropped to such an extent as to receive sufficient play to permit its free guided Weight end to drop to the bottom of its guide 63 to be supported thereby, this operation. completely releases the counter lever 53 and the entire mechanism depending upon it and controlled by it, and permits the lever arms 18 and 23 to swing downwardly to permit the body of the wagon to descend and rest upon the front and rear bolsters! and 6.

When it is required to ascertain the correct weight'of the contents of the wagon, the eccentric 58 is revolved by means -of the handle 62 to raise the hooked free end of the weight or scale beam 59 off the bottom of the guide 63. whereby it is supported when not in operative position. Immediately the weight or scale beam 59 is moved into operative position the force applied to the end of the counter lever. arm 53 by said weight or scale beam 59 moves the levers 57 and 58 upwardly, and these levers being connected to the levers 33 and 34 cause the'levers 18 and 23 to swing pwardly to raise the body of the wagon off the front and rear bolsters 4 and 6. The entire load of the body of the wagon and its contents is transferred to the apparatus and the correct weight thereof is ascertained by a proper manipulation of the weights on the weight carrier 65 and by moving the sliding weight 66 along the beam 59 in the direction required to ascertain the correct weightrwhich is read off the scale on the beam 59.
